RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. §119(e) to U.S. provisional patent application, U.S. Ser. No. 62/051,878, filed Sep. 17, 2014, the entire contents of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Epigenetic regulation of gene expression is an important biological determinant of protein production and cellular differentiation and plays a significant pathogenic role in a number of human diseases.

Epigenetic regulation involves heritable modification of genetic material without changing its nucleotide sequence. Typically, epigenetic regulation is mediated by selective and reversible modification (e.g., methylation) of DNA and proteins (e.g., histones) that control the conformational transition between transcriptionally active and inactive states of chromatin. These covalent modifications can be controlled by enzymes such as methyltransferases (e.g., CARM1 (co-activator-associated arginine methyltransferase 1; PRMT4)), many of which are associated with specific genetic alterations that can cause human disease.

Disease-associated chromatin-modifying enzymes play a role in diseases such as proliferative disorders, autoimmune disorders, muscular disorders, and neurological disorders. Thus, there is a need for the development of small molecules that are capable of inhibiting the activity of CARM1.

The total number of significant decimal digits in a number or percentage does not affect the precision and accuracy of the number or percentage. For example, the numbers “100” and “100.0” are used interchangeably.

When a characteristic peak of an X-ray powder diffraction pattern is expressed in “degrees 2-theta (±0.2)” at Z, where Z is a number, the characteristic peak is at between Z+0.2 and Z−0.2 degrees 2-theta, inclusive.

The term “about X,” where X is a number or percentage, refers to a number or percentage that is between 99.5% and 100.5%, between 99% and 101%, between 98% and 102%, between 97% and 103%, between 96% and 104%, between 95% and 105%, between 92% and 108%, or between 90% and 110%, inclusive, of X. For example, the term “about 100” or “about 100.0” refers to between 99.5 and 100.5, between 99 and 101, between 98 and 102, between 97 and 103, between 96 and 104, between 95 and 105, between 92 and 108, or between 90 and 110, inclusive.

The term “salt” refers to ionic compounds that result from the neutralization reaction of an acid and a base (e.g., compound 109-3). A salt is composed of one or more cations (positively charged ions) and one or more anions (negative ions) so that the salt is electrically neutral (without a net charge). Salts of the compounds include those derived from inorganic and organic acids and bases. Examples of acid addition salts are salts of an amino group formed with inorganic acids, or organic acids, such as gentisic acid, or by using other methods known in the art such as ion exchange. Inorganic acids include hydrogen chloride, hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid. Additional organic acids include acetic acid, oxalic acid, maleic acid, L-tartaric acid, R-tartaric acid, citric acid, succinic acid, fumaric acid, malic acid, and malonic acid. Other salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, hippurate, and the like.

In certain embodiments, the salt is a gentisate.

The term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. In certain embodiments, a pharmaceutically acceptable salt of a compound (e.g., compound 109-3) is a salt described herein, e.g., a gentisate.

The term “solvate” refers to a form of a compound (e.g., compound 109-3), or a salt or co-crystal thereof, that is associated with a solvent, usually by a solvolysis reaction. This association may include hydrogen bonding. Conventional solvents include water, methanol, isopropanol, THF, and acetone. In certain embodiments, solvates are formed using Class 3 solvent(s). Categories of solvents are defined in, for example, the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), “Impurities: Guidelines for Residual Solvents, Q3C (R3), (November 2005). A compound (e.g., compound 109-3), or a salt or co-crystal thereof, may be prepared, e.g., in an amorphous or crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate are capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. Solvates includes both solution-phase and isolable solvates. In certain embodiments, the solvate is a hydrate. In certain embodiments, the solvate is a methanolate (methanol solvate) or isopropanolate (isopropanol solvate). In certain embodiments, the solvate is an acetone solvate or THF solvate.

The term “stoichiometric solvate” refers to a solvate, which comprises a compound (e.g., compound 109-3), or a salt thereof, and a solvent, wherein the solvent molecules are an integral part of the crystal lattice, in which they interact strongly with the compound, or a salt or co-crystal thereof, and each other. The removal of the solvent molecules will cause instability of the crystal network, which subsequently collapses into an amorphous phase or recrystallizes as a new crystalline form with reduced solvent content.

The term “non-stoichiometric solvate” refers to a solvate, which comprises a compound (e.g., compound 109-3), or a salt or co-crystal thereof, and a solvent, wherein the solvent content may vary without major changes in the crystal structure. The amount of solvent in the crystal lattice only depends on the partial pressure of solvent in the surrounding atmosphere. In the fully solvated state, non-stoichiometric solvates may, but not necessarily have to, show an integer molar ratio of solvent to the compound, or salt or co-crystal thereof. During drying of a non-stoichiometric solvate, a portion of the solvent may be removed without significantly disturbing the crystal network, and the resulting solvate can subsequently be resolvated to give the initial crystalline form. Unlike stoichiometric solvates, the desolvation and resolvation of non-stoichiometric solvates is not accompanied by a phase transition, and all solvation states represent the same crystal form.

The term “hydrate” refers to a compound (e.g., compound 109-3), or a salt or co-crystal thereof, that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound, or a salt or co-crystal thereof, is in a definite ratio to the number of molecules of the compound, or a salt or co-crystal thereof, in the hydrate. Therefore, a hydrate of a compound, or a salt or co-crystal thereof, may be represented, for example, by the general formula R·x H₂O, wherein R is the compound, or salt or co-crystal thereof, and x is a number greater than 0. A given compound, or a salt or co-crystal thereof, may form more than one type of hydrate, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R·0.5 H₂O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R·2 H₂O) and hexahydrates (R·6 H₂O)).

The term “crystalline” or “crystalline form” refers to a solid form substantially exhibiting three-dimensional order. In certain embodiments, a crystalline form of a solid is a solid form that is substantially not amorphous. In certain embodiments, the X-ray powder diffraction (XRPD) pattern of a crystalline form includes one or more sharply defined peaks.

The term “amorphous” or “amorphous form” refers to a form of a solid (“solid form”), the form lacking long-range order. In certain embodiments, an amorphous form of a solid is a solid form that is substantially not crystalline. In certain embodiments, the X-ray powder diffraction (XRPD) pattern of an amorphous form includes a wide scattering band with a peak at 2θ of, e.g., between 20 and 70° , inclusive, using CuKα radiation. In certain embodiments, the XRPD pattern of an amorphous form further includes one or more peaks attributed to crystalline structures. In certain embodiments, the maximum intensity of any one of the one or more peaks attributed to crystalline structures observed at a 2θ of between 20 and 70°, inclusive, is not more than 300-fold, not more than 100-fold, not more than 30-fold, not more than 10-fold, or not more than 3-fold of the maximum intensity of the wide scattering band. In certain embodiments, the XRPD pattern of an amorphous form includes no peaks attributed to crystalline structures.

The term “co-crystal” refers to a crystalline structure comprising at least two different components (e.g., compound 109-3 and an acid), wherein each of the components is independently an atom, ion, or molecule. In certain embodiments, none of the components is a solvent. In certain embodiments, at least one of the components is a solvent. A co-crystal comprising compound 109-3 and an acid is different from a salt formed from compound 109-3 and the acid. In a salt, compound 109-3 is complexed with the acid in a way that proton transfer (e.g., a complete proton transfer) from the acid to compound 109-3 easily occurs at room temperature. In a co-crystal, however, compound 109-3 is complexed with the acid in a way that proton transfer from the acid to compound 109-3 does not easily occur at room temperature. In certain embodiments, of a co-crystal, there is no proton transfer from the acid to compound 109-3. In certain embodiments of a co-crystal, there is partial proton transfer from the acid to compound 109-3. Co-crystals may be useful to improve the properties (e.g., solubility, stability, and ease of formulation) of compound 109-3.

The term “impurity” refers to extraneous matter included in a desired substance (e.g., a compound (e.g., compound 109-3), or a salt, solvate, hydrate, co-crystal, amorphous form, or crystalline form thereof). Extraneous matter includes one or more substances that are different from the desired substance. In certain embodiments, the extraneous matter is undesired extraneous matter. For example, when the desired substance is an anhydrous compound, a solvent (e.g., water) included in or with the anhydrous compound is an impurity. When the desired substance is a crystalline compound, an amorphous form of the compound included in or with the crystalline compound is an impurity. When the desired substance is a certain solid form of a compound, a different solid form of the compound included in or with the solid form of the compound is an impurity. When the desired substance is a salt of a compound, a different salt of the compound included in or with the salt of the compound is an impurity. The term “substantially free of impurities” means that a desired substance does not contain a significant amount of extraneous matter (e.g., undesired extraneous matter). What amount of the extraneous matter constitutes a significant amount depends on the subject matter and is understood in the art. In certain embodiments, at least 0.5%, at least 1%, at least 2%, at least 3%, at least 4%, at least 5%, or at least 10% by weight of extraneous matter in the desired substance is a significant amount of extraneous matter. The amount of impurities may be determined using high-performance liquid chromatography (HPLC) with, e.g., an ultraviolet (UV) detector at, e.g., about 214 or about 220 nm. Under suitable conditions, a desired substance and each impurity are separated after HPLC, and the areas of the peaks of the resulting HPLC chromatogram may be determined. In certain embodiments, the weight ratio of the amount of an impurity to the amount of a desired substance is the ratio of the peak area of the impurity to the peak area of the desired substance.

A “subject” to which administration is contemplated refers to a human (i.e., male or female of any age group, e.g., pediatric subject (e.g., infant, child, or adolescent) or adult subject (e.g., young adult, middle-aged adult, or senior adult)) or non-human animal. In certain embodiments, the non-human animal is a mammal (e.g., primate (e.g., cynomolgus monkey or rhesus monkey), commercially relevant mammal (e.g., cattle, pig, horse, sheep, goat, cat, or dog), or bird (e.g., commercially relevant bird, such as chicken, duck, goose, or turkey)). In certain embodiments, the non-human animal is a fish, reptile, or amphibian. The non-human animal may be a male or female at any stage of development. The non-human animal may be a transgenic animal or genetically engineered animal. A “patient” refers to a human subject in need of treatment of a disease.

The terms “administer,” “administering,” or “administration” refers to implanting, absorbing, ingesting, injecting, inhaling, or otherwise introducing a compound, or a salt, co-crystal, amorphous form, or crystalline form thereof, or a pharmaceutical composition thereof, in or on a subject.

The terms “in combination” and “co-administration” can be used interchangeably to refer to the use of more than one therapy (e.g., one or more prophylactic and/or therapeutic agents). The use of the terms does not restrict the order in which therapies (e.g., prophylactic and/or therapeutic agents) are administered to a subject.

The terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a “pathological condition” (e.g., a disease, disorder, or condition, or one or more signs or symptoms thereof). In some embodiments, treatment may be administered after one or more signs or symptoms have developed or have been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of the disease or condition. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms. Treatment may also be continued after symptoms have resolved, for example, to delay or prevent recurrence.

The terms “prevention,” “prevent,” and “preventing” refer to administering a medicament (e.g., compound 109-3, or a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition thereof) beforehand to avert or forestall the appearance of one or more symptoms of a disease or disorder. The person of ordinary skill in the medical art recognizes that the terms “prevention,” “prevent,” and “preventing” are not absolute terms. In the medical art these terms are understood to refer to the prophylactic administration of a medicament to substantially diminish the likelihood or seriousness of a condition, or symptom of the condition, and this is the sense intended in this disclosure.

The terms “condition,” “disease,” and “disorder” are used interchangeably.

An “effective amount” of a salt, co-crystal, amorphous form, or crystalline form described herein refers to an amount sufficient to elicit the desired biological response, e.g., treating a condition. The effective amount of a salt, co-crystal, amorphous form, or crystalline form described herein may vary depending on such factors as the desired biological endpoint, the pharmacokinetics of the salt, co-crystal, amorphous form, or crystalline form, the condition being treated, the mode of administration, and the age and health of the subject. An effective amount encompasses therapeutic and prophylactic treatment. For example, in treating a CARM1-mediated disorder, an effective amount of a salt, co-crystal, amorphous form, or crystalline form described herein may provide a therapeutic and/or prophylactic benefit in the treatment and/or prevention of the CARM1-mediated disorder or to delay or minimize one or more symptoms associated with the CARM1-mediated disorder.

A “therapeutically effective amount” of a salt, co-crystal, amorphous form, or crystalline form described herein is an amount sufficient to provide a therapeutic benefit in the treatment of a condition (e.g., a CARM1-mediated disorder) or to delay or minimize one or more symptoms associated with the condition. A therapeutically effective amount of a compound, or a salt, co-crystal, amorphous form, or crystalline form thereof, or a pharmaceutical composition thereof, means an amount of therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment of the condition. The term “therapeutically effective amount” can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of the condition, or enhances the therapeutic efficacy of another therapeutic agent.

A “prophylactically effective amount” of a salt, co-crystal, amorphous form, or crystalline form described herein is an amount sufficient to prevent a condition (e.g., a CARM1-mediated disorder), or one or more symptoms associated with the condition or prevent its recurrence. A prophylactically effective amount of a compound, or a salt, co-crystal, amorphous form, or crystalline form thereof, or a pharmaceutical composition thereof, means an amount of a therapeutic agent, alone or in combination with other agents, which provides a prophylactic benefit in the prevention of the condition. The term “prophylactically effective amount” can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent.

The term “methyltransferase” represents transferase class enzymes that are able to transfer a methyl group from a donor molecule to an acceptor molecule, e.g., an amino acid residue of a protein or a nucleic base of a DNA molecule. Methytransferases typically use a reactive methyl group bound to sulfur in S-adenosyl methionine (SAM) as the methyl donor. In some embodiments, a methyltransferase described herein is a protein methyltransferase. In some embodiments, a methyltransferase described herein is a histone methyltransferase. Histone methyltransferases (HMT) are histone-modifying enzymes, (including histone-lysine N-methyltransferase and histone-arginine N-methyltransferase), that catalyze the transfer of one or more methyl groups to lysine and/or arginine residues of histone proteins. In certain embodiments, a methyltransferase described herein is a histone-arginine N-methyltransferase.

Solid Forms

Compound 109-3 and forms of compound 109-3 associated with gentisic acid have been found to exist in a variety of forms, such as salts, co-crystals, amorphous forms, and crystalline forms as described herein.

Different solid forms of a compound (e.g., compound 109-3), salt, or co-crystal thereof typically differ in their physical and/or chemical properties due to the arrangement of the molecules in the solid form (e.g., the arrangement of the molecule in a crystal lattice). The different solid forms may even result in different pharmacokinetic and/or pharmacodynamic properties. The salts, co-crystals, amorphous forms, and crystalline forms may improve one or more physical, chemical, pharmacokinetic, and/or pharmacodynamic characteristics (e.g., increased solubility (e.g., aqueous solubility); increased permeability; increased stability; increased ease of formulation, storage, transportation, and/or administration; decreased costs of formation, transportation, storage, and/or administration; increased adsorption; modified distribution; increased bioavailability; increased or decreased metabolism; increased or decreased excretion; increased potency; increased efficacy; decreased toxicity; decreased frequency and/or severity of side effects; and/or increased patient compliance), compared with compound 109-3, an amorphous form of compound 109-3, an amorphous form of a salt of compound 109-3, a different crystalline form of compound 109-3, a different crystalline form of a salt of compound 109-3, and/or a different co-crystal comprising compound 109-3 and an acid.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the salts, co-crystals, amorphous forms, and crystalline forms described herein with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may comprise buffering agents.

Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

The active ingredient can be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active ingredient can be admixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms may comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets, and pills, the dosage forms may comprise buffering agents. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.

The salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions described herein are generally useful for the inhibition of CARM1. In some embodiments, the CARM1 is human CARM1. In some embodiments, methods of treating CARM1-mediated disorder in a subject are provided which comprise administering an effective amount of a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein, to a subject in need of treatment. In certain embodiments, the effective amount is a therapeutically effective amount. In certain embodiments, the effective amount is a prophylactically effective amount. In certain embodiments, the subject is suffering from a CARM1-mediated disorder. In certain embodiments, the subject is susceptible to a CARM1-mediated disorder.

As used herein, the term “CARM1-mediated disorder” means any disease, disorder, or other pathological condition in which CARM1 is known to play a role. Accordingly, in some embodiments, the present disclosure relates to treating or lessening the severity of one or more diseases in which CARM1 is known to play a role.

In some embodiments, the present disclosure provides a method of inhibiting CARM1 comprising contacting CARM1 with an effective amount of a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein. The CARM1 may be purified or crude, and may be present in a cell, tissue, or subject. Thus, such methods encompass both inhibition of in vitro and in vivo CARM1 activity. In certain embodiments, the method is an in vitro method, e.g., such as an assay method. It will be understood by one of ordinary skill in the art that inhibition of CARM1 does not necessarily require that all of the CARM1 be occupied by an inhibitor at once. Exemplary levels of inhibition of CARM1 include at least 10% inhibition, about 10% to about 25% inhibition, about 25% to about 50% inhibition, about 50% to about 75% inhibition, at least 50% inhibition, at least 75% inhibition, at least 80% inhibition, at least 90% inhibition, and greater than 90% inhibition.

In some embodiments, provided is a method of inhibiting CARM1 activity in a subject in need thereof comprising administering to the subject an effective amount of a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein.

In certain embodiments, provided is a method of modulating gene expression or activity in a cell which comprises contacting a cell with an effective amount of a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein. In certain embodiments, the cell in culture in vitro. In certain embodiments, the cell is in an animal, e.g., a human. In certain embodiments, the cell is in a subject in need of treatment.

In certain embodiments, provided is a method of modulating transcription in a cell which comprises contacting a cell with an effective amount of a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein. In certain embodiments, the cell in culture in vitro. In certain embodiments, the cell is in an animal, e.g., a human. In certain embodiments, the cell is in a subject in need of treatment.

In certain embodiments, a method is provided of selecting a therapy for a subject having a disease associated with CARM1-mediated disorder or mutation comprising the steps of determining the presence of CARM1-mediated disorder or gene mutation in the CARM1 gene or and selecting, based on the presence of CARM1-mediated disorder a gene mutation in the CARM1 gene a therapy that includes the administration of a salt, co-crystal, amorphous form, or crystalline form described herein. In certain embodiments, the disease is a proliferative disorder. In certain embodiments, the disease is cancer.

In certain embodiments, a method of treatment is provided for a subject in need thereof comprising the steps of determining the presence of CARM1-mediated disorder or a gene mutation in the CARM1 gene and treating the subject in need thereof, based on the presence of a CARM1-mediated disorder or gene mutation in the CARM1 gene with a therapy that includes the administration of a salt, co-crystal, amorphous form, or crystalline form described herein. In certain embodiments, the subject is a cancer patient.

In some embodiments, a salt, co-crystal, amorphous form, crystalline form, or pharmaceutical composition described herein is useful in treating a proliferative disorder, such as cancer. For example, while not being bound to any particular mechanism, protein arginine methylation by CARM1 is a modification that has been implicated in signal transduction, gene transcription, DNA repair and mRNA splicing, among others; and overexpression of CARM1 within these pathways is often associated with various cancers. Thus, the salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions, which inhibit the action of PRMTs, and specifically CARM1, are effective in the treatment of cancer.

In some embodiments, the salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions described herein are effective in treating cancer through the inhibition of CARM1. For example, CARM1 levels have been shown to be elevated in castration-resistant prostate cancer (CRPC) (e.g., see Di Lorenzo et al., Drugs (2010) 70:983-1000), as well as in aggressive breast tumors (Hong et al., Cancer 2004 101, 83-89; El Messaoudi et al., Proc. Natl. Acad. Sci. U.S.A. 2006, 103, 13351-13356; Majumder et al., Prostate 2006 66, 1292-1301). Thus, in some embodiments, inhibitors of CARM1, such as such as the salts, co-crystals, amorphous forms, and crystalline forms described herein, are useful in treating cancers associated with aberrant CARM1 activity, e.g., CARM1 overexpression or aberrant protein methylation. For example, aberrant CARM1 activity has been found in prostate cancer (e.g., see Hong et al., Cancer (2004), 101:83-89); plays a coactivator role in the dysragulation of beta-catenin activity in colorectal cancer (e.g., see Ou et al., Mol. Cancer Res. (2011) 9:660); and has been linked to estrogen signaling and estrogen related cancers such as breast cancer (see, e.g., Teyssiewr et al., Trends in Endocrinology and Metabolism (2010) 21:181-189). CARM1 has also been shown to affect estrogen receptor alpha (ER-alpha) dependent breast cancer cell differentiation and proliferation (Al-Dhaheri et al., Cancer Res. 2011 71, 2118-2128), thus in some aspects CARM1 inhibitors, such as the salts, co-crystals, amorphous forms, and crystalline forms described herein, are useful in treating ERα-dependent breast cancer by inhibiting cell differentiation and proliferation. In another example, CARM1 has been shown to be recruited to the promoter of E2F1 (which encodes a cell cycle regulator) as a transcriptional co-activator (Frietze et al., Cancer Res. 2008 68, 301-306). Thus, CARM1-mediated upregulation of E2F1 expression may contribute to cancer progression and chemoresistance as increased abundance of E2F1 triggers invasion and metastasis by activating growth receptor signaling pathways, which in turn promote an antiapoptotic tumor environment (Engelmann and Püitzer, Cancer Res 2012 72; 571). Accordingly, in some embodiments, the inhibition of CARM1, e.g., by the salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions described herein, is useful in treating cancers associated with E2F1 upregulation, e.g., such as lung cancer (see, e.g., Eymin et al., Oncogene (2001) 20:1678-1687), and breast cancer (see, e.g., Brietz et al., Cancer Res. (2008) 68:301-306). Thus, without being bound by any particular mechanism, the inhibition of CARM1, e.g., by the salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions described herein, is beneficial in the treatment of cancer. CARM1 overexpression has also been demonstrated to be elevated in 75% of colorectal cancers (Kim et al., BMC Cancer, 10, 197). It has been additionally been determined that depletion of CARM1 in WNT/β-catenin dysregulated colorectal cancer suppressed anchorage independent growth (Ou et al., Mol. Cancer. Res., 2011 9, 660-670). This, in some embodiments, the inhibition of CARM1, e.g. by the salts, co-crystals, amorphous forms, crystalline forms, and pharmaceutical compositions described herein, is useful in colorectal cancer associated with elevated CARM1 expression or dysregulated WNT/β-catenin signaling.
